Abstract: Disclosed is a sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. The sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. In this environment, the sounding reference signal is transmitted through an antenna pattern through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead.

Abstract: A method for activating/deactivating secondary carriers of a User Equipment (UE) in a mobile communication system supporting carrier aggregation is provided. The method comprises, receiving a control message including an activation/deactivation Control Element (CE) in a first sub-frame from a Base station, identifying an activation command or a deactivation command of at least one secondary carrier based on the control message, determining whether a current sub-frame is a second sub-frame or not, performing at least one first operation for the at least one secondary carrier in a second sub-frame, and performing, when the activation/deactivation CE indicates deactivation of the at least one secondary carrier, at least one second operation for the at least one secondary carrier no later than the second sub-frame.

Abstract: Methods and apparatuses are provided for reporting power headroom of a user equipment (UE). It is determined whether a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission is configured. First power headroom information and second power headroom information are, if the simultaneous PUCCH and PUSCH transmission is configured. The first power headroom information and the second power headroom information are simultaneously transmitted to a base station. The first power headroom information is obtained by subtracting a PUSCH transmit power from a maximum UE transmit power in a subframe, and the second power headroom information is obtained by subtracting a PUCCH transmit power and the PUSCH transmit power from the maximum UE transmit power in the subframe.

Abstract: The present invention relates to a method and to an apparatus for optimizing the power consumption of a terminal in a mobile communication system. The method for optimizing power consumption of a terminal in a mobile communication system comprises: a determination step of determining whether there is a need for changing a configuration for a discontinuous reception operation of the terminal; and a transmission step of transmitting, to a base station, a request message for a change in the discontinuous reception operation, if it is determined that the change is needed.

Abstract: A control information transmission and reception method based on a spatial-multiplexing gain, are provided. The control information may be transmitted by obtaining the spatial-multiplexing gain using an E-PDCCH region, and thus, a transmission efficiency of the control information may be improved. The common control information used for decoding the E-PDCCH may be transmitted via a PDCCH, and thus, a base station supporting both a general terminal and an enhanced terminal may effectively transmit the control information. Information associated with an indicator indicating whether the E-PDCCH is to be used during a subsequent resource allocation period may be transmitted, and thus, whether decoding with respect to the E-PDCCH is to be performed during the subsequent allocation period may be determined.
